Grinding machine processing
Grinding machine is a precision equipment for finishing the surface of parts, especially the hardened workpiece.The grinding machines used in mold processing are plane grinder, internal and external grinding machine, coordinate grinding machine (PG optical curve grinding machine).
Xiaoping grinding machine is mainly used to process small-size mold parts, such as precision insert, precision mold, slide, etc.Large - scale grinding machine is often used in large - size template processing.Now, the linear speed of grinding wheel of plane grinding machine and the movement high speed of working table have become the general trend. As a result of using the linear guide rail, linear motor, static pressure screw and other advanced functional parts technology, the movement speed has made great progress, in addition, the grinding wheel dressing technology has been constantly improved.The minimum vertical feed amount of grinding head can reach 0.1 mm, grinding surface roughness Ra<0.05 mm, machining precision can be controlled within 1 mm, realizing ultra-fine grinding.
Mold parts with high precision, good surface finish, and even complex curved surface parts, need to be completed using a high-precision external grinding machine, such as the hatf insert part of the bottle embryo injection mold.Grinding with high speed rotary grinding wheel can be used to process materials with high hardness, such as hardened die steel, hard alloy, etc.Designed for the grinding of medium single part and batch workpiece, the Swiss stalt internal and external grinder is suitable for the customization of individual requirements (external grinding, non-circular forming grinding, thread grinding, internal grinding).
Optical profile grinding machine can grind holes with high precision and various profile shapes.The plotter is used to coordinate the processing, the plotter is used to depict the required processing graphics on the film, the film is attached to the projection screen and calibrated, the processor will be based on the film on the molding process.Optical projection grinding is suitable for forming grinding of high hardness materials, such as tungsten steel or hard alloy workpieces, and occasionally some high speed steel workpieces.General processing connector punching die with tool and punch, the terminal, precision half stroke punch, the lower die into the block and off the plate into such as the workpiece.
The famous optical curved grinding machines include HAUSER of Switzerland, MOORE of America and AMADA of Japan.Japanese AMADA optical curve grinding machine has a spindle speed of 30,000 rotation and the machining accuracy is within 2mm. The minimum inner R Angle of the machining is R0.03mm and the outer R Angle is R0.02mm. The thinnest part of the processing special-shaped punch can reach 0.06mm.
